AC unit change-out

Signs that indicate the need for an AC unit change-out

If you are not sure about an air conditioning unit replacement, here are some signs that could suggest that it is time to do it.

The unit makes an uneven cooling:

If when you turn on your HVAC system, you notice that there is only cooling in some areas of your building, but other rooms are warmer, this indicates a malfunction.

You have an old unit:

If you have between 10 or 15 years with the same AC unit, this could be time to make the change, as over time, HVAC systems become less efficient and, even worse, suffer constant breakdowns, increasing repair costs.

Your electric bill increased:

If the unit is not working correctly, it can improve the kW consumption per month in the building, which makes it less energy efficient, and implies a higher cost in the long run.

You hear strange noises:

One of the signs that least notice the owners are the noises and even strange smells when they have their AC units on, and these can be severe problems, which could alert you about a faulty motor or electrical failure.

Your AC is damaged frequently:

If your air conditioning system demands continuous repairs, this is a sign that its life is ending and, at any time, will stop working.

Preparing for an AC unit change-out

Understanding that a new HVAC system installation is a multi-phase process can help make the replacement experience easier and more comfortable and ensure an efficient job:
Let’s take them one by one!

Select a licensed HVAC contractor:

More is needed that the company has a good reputation; you need to have the skills and qualified technical expertise to perform a professional job with all the safety guarantees.

The unit makes an uneven cooling:

If when you turn on your HVAC system, you notice that there is only cooling in some areas of your building, but other rooms are warmer, this indicates a malfunction.

Evaluate the size of your unit

The contractor should help you select the best AC unit option considering the size of your home or building. In addition, he should consider factors such as the type of insulation, specific preferences according to the purpose of your building, etc.

Evaluate your existing unit:

Before proceeding with the replacement, the contractor must examine your HVAC, ductwork, wiring, and other aspects to see its condition and what needs to be removed, and also to see what areas are vulnerable in your property.

Establishing a budget:

A professional contractor will tell you the cost of the new unit, materials, ductwork, wiring, and installation cost and stick to it after assessing the area.

I have used other HVAC companies in the past and discovered Advanced Air Systems as a recommendation. I had used another HVAC company and after multiple visits and not fixing the problem and paying a lot of money someone recommended Advanced Air. Now I will only use Advanced air from now forward. Don't look any further and know they're a great company

I have been a client of Advanced Air for over 10 years at the property I work at and that speaks for itself. The professionalism and service is unmatched from the office to the technicians, managers and all the way up to the President. Whenever an issue arises, they always arrive promptly and keep you updated with eta's for parts, repairs, etc. In my opinion, they are the most reliable AC company in SoFlo, as I have watched residents use other companies and not been satisfied with their service multiple times. I always recommend Advanced Air to new owners because I trust them and can always depend that what they say needs to be done, is done both on time and at the price agreed upon on the proposal.They ALWAYS are reachable and willing to help. Special thanks to Mr. Paul Murphy, Installer Paul, Tech. Luxson and Sergio and Jeff for all yall do!

I had the pleasure of working with Leena and her crew at the Riverside Hotel over the summer. Excellent communication throughout the whole project! Her crew was not only professional and courteous they were also very efficient! Having confident people on a big project such as ours was awesome! I look forward to future projects in the future. Thank you Leena and Advanced Air !!
